What are the side effects of Norfloxacin?
Norfloxacin may cause a range of adverse reactions, from mild to severe.
Common Side Effects: - Nausea: mild to moderate upset stomach. - Diarrhea: loose stools, sometimes watery. - Headache: transient cranial discomfort. - Dizziness: sensation of light‑headedness. - Abdominal pain: cramping or discomfort. - Rash: mild skin irritation or redness.
Serious or Rare Side Effects: - Tendon rupture: sudden tendon pain or loss of function. - QT interval prolongation: potential cardiac arrhythmia. - Severe allergic reactions: anaphylaxis, swelling, or hives. - Clostridioides difficile infection: severe colitis with watery diarrhea. - Hepatic dysfunction: jaundice or elevated liver enzymes. - Photosensitivity: heightened skin reaction to sunlight.
What precautions apply to Norfloxacin?
Before prescribing Norfloxacin, clinicians should consider several safety factors. - Renal impairment: assess kidney function and adjust dose if necessary. - History of tendon disorders: avoid use in patients with prior tendon injury. - Concurrent antacids or supplements: separate administration to ensure absorption. - Pregnancy and lactation: use only when benefits outweigh potential risks. - Known hypersensitivity to fluoroquinolones: contraindicated. - Store at ambient temperature: keep in the original container, protect from moisture.
What does Norfloxacin interact with?

Major Interactions (Avoid): - Theophylline: increased plasma concentrations may cause toxicity. - Warfarin: enhanced anticoagulant effect, raising bleeding risk. - Ciprofloxacin or other fluoroquinolones: additive QT prolongation. - NSAIDs (e.g., ibuprofen): heightened central nervous system adverse effects.
Moderate Interactions (Monitor Closely): - Antacids containing magnesium or aluminum: reduce norfloxacin absorption. - Iron supplements: diminish oral bioavailability. - Glucocorticoids: increase risk of tendon rupture.
